JOSEPH CZERWINSKI, OF CHICAGO, ILLINOIS.

BELT-BUCKLE.

Application filed April 11, 1921.

To all whom it may concern Be it known that I, Josnrrr CznRwINsKI, a citizen of the Republic of Poland, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Belt-Buckles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to e accompanying merals of reference marked thereon, which form a part of this specification.

This invention relates to buckles of the sort ordinarily worn with belts.

It is an object of this invention to provide a buckle which shall be readily secured in place and shall maintain its grip upon the belt without working loose.

It is a further object of this invention to provide a buckle which will not materially lessen its grip upon the belt through wear due to repeated fastening and unfastening of the buckle.

It is a further object of this invention to provide a buckle which is readily fastened and will not become accidentally unfastened.

It is a further object of this invention to provide a buckle with a pair of lugs which shall act to yieldingly retain the fastening part of the buckle in fastening position.

It is a further object of this invention to provide a buckle which can be adjusted for use with belts of different thicknesses.

It is a further, object of this invention to provide a buckle of the class indicated which shall not depend upon motion past a dead center to render secure the grip of the buckle upon the belt.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Fig. 6 isan enlarged view of a lug on the side of the buckle.

s shown on the drawings: The buckle has a front plate 1 which may Patented July 26 1921.

ave ornamentation of any desired kind.

he two edges of this plate are turned up as shown at 2 to provide a housing for the belt and the working parts of the buckle.

ounted in the side walls 2 is a pivot pin 3. The ends of this pin are secured in the walls 1n any convenient manner, as for example y being upset.

he movable fastening the buckle consists of a from the rest of the lever in order that they may pass upon the opposite side of the pin .3 as illustrated at 9. The arm 6 of the lever is straight for most of its length but near the pm 3 it is bent forming an. angle 10 so that that portion nearest the pin is approximately parallel to the arm 7. The pin 3 is thus housed within a U-shaped part of the member 5. The outer end of the arm 6 is providedwith a slotted portion 11 for the passage of th looped end of the belt. The arm 7 is somewhat longer than the analogous part of similar buckles heretofore used, so that it is not possible for the arm 7 to pass beyond a deadcenter to a position where the pressure of the belt would tend to keep it in fastening position. The contact of the arm 7 with the belt will stop it before the dead center is reached.

pon the side walls 2 at the end and where the arm 6 emerges is provided a pair of lugs 12. The lugs are bent inward from the side walls 2 so that they are substantially straight they are s the belt 16 and at lugs 12 raised or releasing position illustrated in the drawings.

has been tightened to the desired degree the which is not When the belt lever is moved to the illustrated position by pressing the arm 6 toward the front plate 1. This brings the arm 7 against the end of the same time forces the arm 6 between the lugs 12. V

The side walls 2, being somewhat elastic, yield to permit the passage of the member 6 between the lugs 12. The arm 6 may itself be somewhat yielding to facilitate this passage. The work-of forcing the walls apart is rendered easy by the additional circumstance that the slope of the part 13 of the edge of the lug is very gentle. As the lever is forcedpast the lugs this edge acts as a cam to force the wall 2 outward and the "edge of the arm 6inward. The pull of the looped end .15 of the belt on the arm 6 tends to keep the lever in the illustrated position. If any movement of the wearer of the belt should lessen the pull upon the belt so that there should be a tendency of the lever to depart from the illustrated position, the will prevent such motion, holding the lever to the illustrated position.

hen it is desired to unfasten the belt 7 the lever is ,positively moved to the unfas 7 force of the sides 2 the belt, even though tening position. To do this the arm 6 must be forced past the lugs 12 against the elastic and of the arm itself. Because the cam portion 14 of the edges of V the lugs is steep, considerable effort is required in order to move the-lever in this direction; ment of the lever to releasing position is eX- tremely unlikely.

'Since the arm 7 does not go past the dead center in the fastening movement of the lever, the elasticity of the material ofthe lever will cause the arm '7 to effectively clasp repeated use of the buckle at the same spot .on the belt SllOl ld wear the material of. the end 16 so that it becomes thinner than when first used. 7. Also the lever 5 maybe made of some metal that is easily bent so that the angle the arm 7 makes with 6 canbe changed from time to time, if desired, vto accommodate a worn belt'or to accommodate material of different thickness if the buckle is used upon a 7 different belt.

must not however of this invention, and

The-metal of the lever 5 bend so easily that it will fail to hold the belt firmly. even after repeated use. The apex of theangle 10 forms a very convenient rest for a. tool such as wouldbe-nsed in bending the arm 7 when such bending is desired.

I am. aware that. numerous details of construction may be varied through a wide range without departing from the principles housing, and

consequently, accidental move I therefore do notpurpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a buckle, an elastic housing, a clamping lever pivotally mounted in said lugs on said housing yieldingly engaging said lever whereby the accidental displacement of said lever from clasping position is prevented;

2. A buckle comprising a housing of resilient sheet metal, a sheet metal clasping lever mounted in said housing, lugs on the walls of said housing engaging the edges of said lever, the edges of said lugs being oblique to the sides of said housing and forming a smaller angle with the walls of the housing on the side of the lugs toward the mounting of the lever than on the other side of said lugs.

3. A buckle. comprising a housing of resilient sheet metal, a sheet metal clasping lever mounted in said housing, lugs on the walls of said housing engaging the edges of said lever, the edges of said lugs being forming a smaller angle with the walls of the housing on the side of the lugs toward the mounting of the lever than on the other side of said lugs, the plane of said lugs being parallel to the plane of said lever.

4a. In a belt buckle, a trough-shaped front plate, a clasping member pivotally mounted in said trough, and lugs on the sides of said trough past which 7 the clasping member must be sprung to bring the buckle to fas-. tening position. 7

5. In a buckle, two parts pivotally connected together, a lug, one of said parts cngaging the other part, and cam edges on said lug. for. permitting thelast named part to be sprung past'said lug, the portion of said edges contacted by the moving part when traveling in one direction having a more gentle slope than the portion contacted by the moving part when traveling in the other 7 7 direction V p 6. In a belt buckle, a. clasping lever comprising two arms extending on the same side of the fulcrum, one of said arms being longer than the other and being bent sothat the portion of it nearest the fulcrum is parallel to the other arm and the remainderv of it makes an angle with first named portion, the apex of said angle being adjacent the end of the shorter arm.
